Just days before a run-off presidential vote in Ukraine, political tension is boiling over.
Former Prime Minister Yulia Tymoshenko is threatening to call for street protests if she suspects fraud by her rival in Sunday’s vote.
“If Viktor Yanukovich wants an honest fight we are ready to compete with him,” she said. “But if he seeks to cheat, we will be able to rebuff him in a way he has never seen, even in 2004.”
Tymoshenko led street protests in 2004 in what became known as the Orange Revolution. This was against the victory of Yanukovich, who was backed at the time by the Kremlin.
This election is seen as crucial for the future of the former Soviet nation, which has had difficult relations with Moscow over gas prices.
The economy is in trouble, with an International Monetary Fund bail-out programme currently suspended.
Ukraine also has ambitions to join the European Union, and the result of the weekend poll could determine how far that project proceeds.
